Howto Work And Manage Backup Log Files???
Apr 13, 2004
Hello everybody,
I have run into some problems with logfiles and backup logfiles (MS SQL server). I have read much about them but uptil now I dont seem to grasp how it works. Specially the part of working with backup log files.
Can someone please help me with this?
What I want todo is to create backup log files, so I can restore the database to any point in time before a failure occured. But using this method create's a problem with the backup log files. They get very big.
So how can I use backup log files without getting to large backup log files?
How can I shrink on a regular basis the backup log files and still be able to restore the database?
Please help.
Best regards,
Marc Janssen,
:)

Hi all,
I have created a package which import data from excel file and do some technical & business validation on the data. My package has about 20 control flow items. Now I'm asked to handle a second (and probably more in the future) excel file format (columns name are different, some fields are murged in one single column...).
I definitely don't want to create a different package for each excel file format. But I can't find a way in the control flow to execute a particular DataFlow in one case and another DataFlow in other cases. Typically I would like to evaluate an expression an depending on the result execute a DataFlow or another one. Even in a given DataFlow I cant find a way to have a condition and process different Excel Source depending on an expression result. Or it would be good if I could say to my Excel Source to discover the columns name and types at runtime and let me manage the columns manually in the data flow. Is that possible ? I know SSIS manage metadata on the columns based on the data source is there any way to manage the metadata manually ? I coulnd't find anything about that in BOL.
I guess an easy workaround is to have a different package just to import the different excel files in a common staging table and each package calls a single package which contains all technical & business validation.
Any help will be appreciated.
Kind regards,
SĂ©bastien.

I have the need to delete old backup files via TSQL job. Found this solution online:
PushD "
emoteservershareDIFF" &&(
forfiles -m *DIFF*.sqb -d -1 -c "cmd /c del /q @path"
) & PopD
It works remotely if I run it via command prompt. But when I add this to a TSQL job on my remote SQL instance, it runs without deleting anything. What I'm missing?

Currently we use a SQL maintenance plan to do a full backup of all our databases daily (about 40 databases on our production server). As you can imagine, this eats up disk space quickly so currently we manually zip the backup files and/or move them to an archive drive. I considered writing an application to walk through the backup folder structure and zip any .bak file it finds, but I know there are some third party tools out there that will backup/restore a MS SQL database.
I was wondering if any of these also zip the backups once they are created. Any recommendations or suggestions are welcome.

I scheduled automatic backup process but its only showing backup of the only one .sql file in the backup folder. Other created .sql files are not backed up. Why is it so?

I've been having some trouble keeping my log file size under control due to some off-hours data loads. Currently, while updating some certain tables, the data base is still in "Full" mode, which of course makes the log file grow accordingly.
Today I figured out that, given the current scenario, in order to shrink the log file back down (after the table update), I have to (1) backup the log file, (2) shrink the log file, (3) backup the log file again, and (4) shrink the log file again. My question is: why do I have to do two iterations of backup / shrink? Why does it not work with one iteration? I just want to better understand the architecture and functionality.
Also, would there be a better way for keeping the log file size under control? If I switched the database to "Simple" mode to load the data, would that work any better?
If so, what might be the best methodology?
Thanks in advance for any responses.

Currently we are running a full backup on Fridays and differentials monday through thursday. With the Logs being truncated. we are using Veritas 10d with a 5 tape auto loader.
As far as recovery goes will this be sufficient?
we have about 40 users doing normal work hours.
My main concern is the transaction logs and making sure that I will be able to recover my data.
also we do not have an open file option and cannot do backups during the day, only at night.
Thanks in advance :D

I have created an Integration Services package on my development machine. The package contains a configuration file witch let's say is stored in c:projectsMyIntegrationServicesProjectmyConfigfile.dtsConfig (on my dev machine).
Then I have another "Production" machine where I import the SSIS package into an SQL database. I then create an sql-job with only one step, to run my SSIS package. This works fine if I configure the step to be an "SQL Integration services package" and configure it to use my configurationfile.
However I would like to configure this package as a CmdExec step. In the commandline, I specify /CONFIGFILE "d:....myConfigfile.dtsConfig" (the correct path on the prod machine). But it seems to be ignored, because when I execute the package I get an error telling me that the configuretion file c:projectsMyIntegrationServicesProjectmyConfigfile.dtsConfig cannot be found.
What I try to say is, it seems like it ignors the config-file I specify on the command-line and tries to reach the config-file on a location that's probably stored somewhere in the SSIS package from the time it was created on my development machine.
Is there a way around this?

Backup Log ..... with no_truncate -- How to get it to work.
Applicable to SQL Server 7.0 Date 8/14/00 andrews_gary_w@solarturbines.com
Introduction to the "Backup Log …….with no_truncate" feature of SQL Server 7.0.
On occasion a database may become corrupt or a database file may be inaccessible. Ideally, in these cases you want to be able to restore and recover the data back to the current point in time.
This requires that the Transaction Log be backed up prior to the restore process beginning.
Microsoft has provided the "Backup Log ……with no_truncate" feature for use in cases such as this. However, this feature works only under very specific conditions and thus is the topic of this document.
Background.
When a database is defined, it always has a primary file group. In some cases this may be the only file group defined for the database. The primary filegroup contains, at a minimum, the system tables for the database being defined. The systems tables hold metadata describing the database. Where no other filegroups have been defined, the primary file group will also contain the user defined tables/indexes.
Essential requirement
"Backup Log …… with no_truncate" must be able to access the "metadata" located in the primary file group, or it will not work. This also means that this part of the database must not be corrupt or that the file containing this part of the database must not be inaccessible.
Specific conditions required for "Backup Log ….. with no_truncate" to work.
a. The database needs to be defined so that the user tables/indexes are contained in one or more file groups other than the primary filegroup.
b. Logging of changes to the database must be in effect.
c. A full backup must exist
d. Changes are made (logged) to the user database.
e. No non-logged operations must have been performed since the last full backup.
f. The primary filegroup file(s) must be available.
g. The primary filegroup data must not be corrupted. Or at least the portion needed by the backup operation must not be corrupted. I am not 100% sure about this issue.
h. The data in the filegroups other than primary may be corrupted or these files may be completely missing.
Process to restore/recover.
a. When problem detected (data file(s) inaccessible or database is corrupted), if primary filegroup is accessible, then perform the Backup Log …. with no_truncate.
b. Then perform the restore process using the "with replace" option for the database. This will get back any missing file(s) and recover you right up to when the last log backup was taken.
c.Post restore/recover process, your database will not be corrupt or missing any data file(s)
Bottom line
To achieve maximum recoverability, the following is recommended.
a. Define databases so that user data is not put in the primary file group.
i.e. Define not only a primary filegroup, but also one or more "other" filegroups.
b. Place user data in the "other" filegroup(s), NOT in the primary filegroup.
c. Place the primary filegroup on a disk drive separate from the "other" filegroup(s).
d. Place the log on a disk drive by itself.
Under the above scenario, at least three different disk drives would be needed to accommodate a single database.
Some sources recommend you put the primary file group and the transaction log on the same disk drive (mirrored). This would of course reduce the maximum number of disks needed to two. This topic, from my perspective, is another issue to be separately addressed and thus is not covered any further in this document.
Remember, even if the database files are isolated as recommended above:
a. Should the primary filegroup file(s) be inaccessible, then the Backup Log …. with no_truncate option will not work.
b. Should the primary filegroup file(s) be corrupt, then depending on where the corruption is determines whether or not the Backup Log ….. with no_truncate option will work.

I have SQL 2005 on 64 bit cluster OS is Windows server 2003 SP2.
We have full-text enabled on one table of the database. It has doc,xls,pdf and swf type of documents. Now full text works for word and excel docs but not for pdf files.
I searched online and found two commands to execute after installing Adobe 6.0 ifilter. I did it last week and then server was rebooted last weekend so it restarted all the services
exec sp_fulltext_service 'load_os_resources', 1
exec sp_fulltext_service 'verify_signature', 0
still pdf full text search is not working. Does this ifilter from Adobe works for 64 bit?
many errors as below are loged into the log file

I am able to perform full text searches if I inform SQL Server the file is a text file but when I set the correct type as a csv the file does not get indexed.
Also nocticed that I have two IFilters one that comes with SQL and the other with Office they have the same name and just the one that is on system32 handles CSV files, office files are processed correctly.
This are the IFilter locations:
C:WINDOWSsystem32offfilt.dll
C:Program FilesMicrosoft SQL ServerMSSQL.4MSSQLBinnofffilt.dll
I have a valid CSV but when I run the FiltDump.exe command I get:
C:Temp>FiltDump 1075555.csv
FILE: 1075555.csv
Error 0x80030050 loading IFilter
This is the type of error log I get from SQL Server:
2007-11-20 15:30:18.46 spid24s Warning: No appropriate filter was found during full-text index population for table or indexed view '[FileStorage].[dbo].[Document]' (table or indexed view ID '6', database ID '162099618'), full-text key value 0x00000002. Some columns of the row were not indexed.
I will appreciate any help provided.

I used the toolbox to select maintenance cleanup task to create the job to do this. In reading similar notes regarding this problem, some people mentioned that there was a choice to include subfolders. I do not have this choice. When I execute select @@version I get Microsoft SQL Server 2005 - 9.00.3042.00 (X64) Feb 10 2007 00:59:02 Copyright (c) 1988-2005 Microsoft Corporation Enterprise Edition (64-bit) on Windows NT 5.2 (Build 3790: Service Pack 2) .

I am running the latest MSDE with the SQL Server 2000 client tools on
Windows 2K Server on my production server. I have a simliar setup on my
development machine except it is running Windows 2K (non-server). I
have the same issue on both machines (I am wondering if it is related
to the structure of the database). When I open Enterprise Manager,
connect to the server, navigate to the Management folder, and add a new
management plan, I experience the following error.
I create a management plan that includes nothing but a complete
database backup (i.e. no reorganization of index pages, logging, etc.).
I set the backup schedule to occur every Sun at 12:00AM and hit OK.
Sometimes I get the following error :"Error 8114: Error converting data
type int to tinyint" sometimes not. Either way, though, the same thing
happens, the schedule for the backup is not saved. If I reopen the
management plan and go to the "Complete Backup" tab, there is no
schedule in the schedule box.
I have found this link:http://www.technologyone.org/new-4581847-3733.html
Which appears to be the same issue that I am having, however, there is
no resolution there. I was wondering if anyone had any ideas.

Hello
I have restored a SQL 2000 backup of my database, ever since my web applications are unable to use any of the stored procedures.
I get the following error:
Could not find stored procedure 'xxx'.
If I use enterprise manager and go to the procedures tab the procedure appears there.
Any ideas what is up?
PS: The username has been changed, before the backup it was "user1" now its something else. For some reason it still shows that the procedure object is owned by "user1". Could this be the problem?
Thanks in advance.

I am doing a complete backup on a sql 7 db and then doing a completerestore (with overwrite existing db) on a sql 2000 server. This is nowour hot standby server. I have the process automated and it worksgreat. The only problem I have now is the logins dont work.I have tried running EXEC sp_change_users_login 'Report', and thelogins appear.However, when I run EXEC sp_helplogins 'joe', the results are empty.So, I am guessing all I need is a sp that will re-associate my loginswith the correct db and grant the appropriate permissions.If anyone has any ideas that would be great.I have also considered doing a log ship instead of a full backup andrestore. Does anyone have any suggections or good examples of how tomake that happen?Thanx

hello! can you take a look at my question?
We use ARCServe to backup exchange server file (priv1.stm and priv1.edb) every night. When I select both of the files and start to back up using ARCServe. It showed me that Backup Operation Successful.
When I check the files, it didn’t backup both of the files. I don’t know why. Do you know how to backup these two files?
Many thanks.

Hi,We are about to install MSSQL Server 2000, on a Windows XP HomeMachine. However, we have servers we could set routine backups of filesto be done to. What what be the best way of doing this?Is there functionality in SQL Server 2000, where we can say dump alldata definitions, accounts, and data to files on this drive at regularintervals?What other suggestions do you have apart from obviously the usual RAID,and Tape Drive stuff?ThanksDavid
